Z_ normals / marked points / solid surfaces

NormalsIn Z8, the normals display is in object attributesIs it possible to assign a keyboard shortcut to this command?(In Z673 the display of the normals was at the level of the display options and thus shortcutable like the other options (points first points etc.)

Marked pointsIs the concept of "marked points" completely removed?(marked points were used in skinning operations)

Solid surfacesHave the solid surfaces been removed in Z8?Do you know why ?A priori the solid surfaces loaded in Z8 (Z673) are converted into single surfaces.(Well it's true I did not use it often ...)
